Xorg - Buildroot distribution - chip XGI Volari z9s

[Grzegorz Wrzesiński]

Have you found a solution already?

I use icop vdx-6326 and LCD-AU084-SET (resolution 800x600),
my own linux distribution base on fedora 11 rpms and
xgiz_drv.so (download from www.sis.com) (the key option in xorg.conf was 
"Device" Option "AccelMethod"  "exa")
In this configuration Xorg works fine.

PDX-089T has the same Vortex86DX and Volari Z9s display chip, but after 
startx I got
Panel Size (1024, 600)...
(EE) XGIX(0): ERROR
(EE) XGIX(0): No valid modes found
...
(EE) Screen(s) found, but none have a usable configuration

I found that xgiz does not support resolution 1024x600.
So...
Have you found a solution already?
